Abstract
This paper describes an instrument which was developed to make graphic records of generator revolutions and time, as the generator slows down under the action of its losses during retardation tests. The construction of speed — time curves from the records thus obtained is outlined. The principle of numerical differentiation is discussed and its application to the determination of the slope of the speed — time curve is pointed out. A complete example illustrating the application of this principle is included in the unabridged paper.
